*4.9. Film Application in Corn Oil Packaging*

The film specimens were stored at 50 ◦C for 10 days after being wrapped in line rope and placed on top of glass bottles containing corn oil. On days 0, 2, 4, 6, 8, and 10, a sample of 5 mL was removed from each glass tube in order to calculate the PV and TBA values using the technique outlined by Elsebaie et al. [63]. The analysis was carried out three times, and the average values were provided. A glass container with no film was applied as a control.
